In the first debate, climate change wasn’t mentioned once. Candidates talked about the economy–but never the fact that climate change could cost us more than $380 billion by the end of the century, according to the New York Times.

And they talked about health–but not the fact that climate change could claim more than 12,000 lives by 2100.

This despite a recent Yale University poll showing more than 50% of registered Republicans believe in climate change, and that we need to do something about it.
